Many years ago, on my first trip out to an oil platform as a rotorcraft student in a 206L, I had a moment of terror when my peripheral vision caught sight of smoke streaming out of the overhead just behind me. Were we about to go down in the Gulf of Mexico 80 miles from shore?
It was, of course, just condensed vapor from the A/C ducts. Scared the heck out of me for a second.
